A witty remark thought of too late, on the way home; the clever comment you wish you had delivered
"When he bragged about sleeping like a baby, I should have added the bit about waking up crying every two hours, but that's just esprit de l'escalier. At the time I just nodded and said nothing."
About the Word:
From the French for "staircase wit," this phrase was coined by 18th century encyclopedist Denis Diderot. As a simpler alternative to esprit de l'escalier, English speakers sometimes use escalator wit.
